Comments seem to be focused on whether this is good or bad. The argument for good sounds suspiciously like the (all invalid) arguments for hunting, that hunting is somehow conservation, because if game not hunted, it would reproduce beyond the point the environmental resources could support their numbers, and they will all suffer greatly by starving. So, if these generous and selfless bitcoin mining individuals were not using residual methane from old wells to mine bitcoin for their own self-interests, then the methane would be released into the atmosphere, and everyone on Earth would be worse off. When you hear these individuals speak in support of themselves, all you will hear, over and over again, droning out your ability to discern if what they're saying makes sense, is, "it's win-win. It's really a win-win. So it's a win-win," and the only message you need take with you is that it is a win-win. I don't know if there are lesser evils here, but the smell of bullshit is overwhelming.
